Where do you hook up an engine idle solenoid?

Hi All,
I have a 73 Charger with a 440 and aftermarket air conditioning
I have been staring at my 73 service manual for hours and I get 3 different schematics.
Page 8-148, figure 16-65 shoes the idle solenoid wire going to a
3-way splice to bulkhead connector 23, the ignition ballast and the alternator regulator.
Page 8-148, figure 17-65 shows the idle solenoid wire going to a 3-way splice that goes to the electronic ignition control, alternator regulator and the ignition ballast.
Page 8-129 shoes the idle solenoid wire going to the middle field (F) connection on the alternator.
and Page 8-128 shows the idle solenoid wire going to the middle field (F) connection on the alternator.
Perhaps this is all the same way, just executed differently.
Can anyone show me a picture of their set up?
are they all in effect the same connection?
Any help or better suggestions would be appreciated
thanks
Vic

If you want it "on" all the time when the ign is on/eng running then I would just solder it into the ign1 "run" blue wire circuit that feeds the reg/alt field/ballast at a good convenient point for aesthetics. EDIT If it is only supposed to be operational when the AC is on then I would T into the feed wire for the AC compressor

Robert,
I have read some where that tapping into the A/C compressor feed causes the solenoid to cycle on and off with the compressor. The main complaint was that if you are stopped in traffic, and the A/C cycles off and on, you have to blip the throttle every A?C cycle to get the solenoid to hold.
If that's just the way things were back in the 70s, I can live with that.
But, ideally I would like activate the solenoid every time I switched the A/C on at the dash (regardless of that the compressor is doing)
thanks

Yeah I dont know AC so that might be the case. You might just wire a seperate on/off toggle switch as you mentioned to have direct control of it, a seperate fused line
